To all whom it may concern:

Be it known that I, CrmRLEs U. Glut rs- LEY, a citizen of the United States, residing in the city of Louisville, county of Jefferson, and State of Kentucky, have invented a new and useful Improvement in Coin- Controlled Fluid-Dispensers, of which the following is a specification,

This invention relates to coin controlled fluid dispensers, more particularly to that class adapted to be operated only after the deposit of a coin.

An object of this invention is to (provide a device of the character described which may be placed in parks or other places much frequented by the public, wherewith individuals may serve themselves.

A further object is to provide a device as characterized which will be economical in construction, durable in service and cilicient in operatlon.

With the foregoing and other ob]ects in view, the invention consists of the novel construction and arrangement of parts illustrated in the accompanying drawings (comprising two sheets) which form a :part of this specification, wherein is set forth an embodiment of the invention, but it is to beunderstood that such changes and modifications may be resorted to as come within the scope of the claims appended hereunto.

In the drawings wherein similar reference characters designate like :parts in the several views, Figure 1, is a front elevation of an embodiment of the invention, parts being broken awayto show the construction; Fig. 2 a central vertical transverse section, on an enlarged scale; Fig. 3 a detached detail (on an enlarged scale) partly in elevation and partly in section, of the operating mechanism; Fig. 4, a rear elevation (with parts omitted) of Fig. 3, and

5, a top plan view of th device.

The invention comprises a base --11-, which may be set in the ground, the-top be ing flush with the surface and a column -l2- erected centrally thereon. The base is preferably rectangular and is c0nstructed with the inner and outer walls 18, 1-l.- which define a space which may be filled with a suitable non conductor of heat 15. The column 12 is likewise constructed with double walls and the intervening space filled with an insulating medium. A tank --16-, for the reception of a fluid to be dispensed, is disposed in the Specification of Letters Patent.

base directly under the column, and may extend upward thereinto. The space on each side of the tank is for the reception of ice which may be placed therein by raising hinged lids -l7. Vertical rods -18 serve to prevent the ice from contacting with and damaging the tank. A drainage pipe -19 provides an overflow. It

.will be observed that the chilled water has free circulation all around the tank. A feed pipe -22- leads upward from a point near the bottom of the tank to aconnection with a pump 23-- at the rear end thereof. A delivery tube -24 leads from the pump and terminates in a faucet -25- positioned exterior of the column in a recess, or alcove 26-, over a basin 27-- from which a drain tube 28 leads. The pump is pivotally connected to the rear wall in order to permit of a slight oscillatory movement incident to. its operation. A short length of rubber hose, or tubing -29-- is interposed in the continuity of the feed pump rod -35- is connected to a stud -36- near the outer end of the lever -3l-. A bar -31 is slidably mounted on the inner side of the front wall just above the bracket 32.. It is preferably angular in shape, and one leg -38 thereof overlies a slot -39- in the wall, the bar be- --4:0- the head l1- of which bears on th outer surface of the wall, and a handle -42- near the lower end, a flange l8- ins; held in position by means of a pin of which bears on the outer surface of the wall. The handle furnishes means whereby the bar may be slid upward, and a spring -t4rserves to return it to its normal position. An arm -4l-5- is pivotally connected respectively with the upper end of the "bar 37, and with the lever 31. The arrangement being such that vertical rectilinear movement imparted to the bar 37 will through the medium ofthe arm 45, draw back the lever 31, and with. it the pump rod. The pump is so proportioned that at each full outward stroke of the pump rod. a given amount, say a half pint of fluid will be drawn into the pump. As soon as the handle is released the spring tends to return the parts to their normal position, forcing the fluid out of the pump but a check valve l6- prevents its return into the tank, and the faucet prevents its escape through the delivery pipe until a valve lever l7 is depressed, when it may pass therethrough into a receptacle held under the faucet by a vendee. The lever 31, is provided on its inner, or free end with a notch l8 adapted for the engagement therewith of a tooth, or projection -4:9 which extends from the lower end of a dog 50-. The dog is pivoted at a point 51 above and forward of its point of engagement with the lever, so that it falls by gravity, the arrangement being such that the lever cannot be moved while the dog is in engagement therewith. A heel 52 of the dog contacts witha transverse bar 53- and limits the downward movement of the dog. When the dog is in its normal position a lateral projection, or ear -54 thereon obstructs th exit from a coin chute 55 which extends inward and downward from a point on the exterior of the front wall. When a coin is deposited in the chute it rolls downward therein until is is stopped by the ear of the dog. The bottom wall of the chute is cut away at 56, at the lower end thereof to permit a coin 57 which has been stopped by the dog, to drop therethrough on to the arm 4:5 which lies in the same vertical plane as the chute, and at that point is close thereto, and is provided with a concave depression 58- for the coin to rest in. The arm is connected with the lever 31, by means of a slot -'59 in the arm, which fits over a pin 60- projecting from a side of the lever, an interposed washer 61-- spacing them apartso that the lever will pass clear of the chute. The arrangement is such that when the bar is raised, an initial movement is imparted to the arm, the extent of which is limited by the length of the slot, before it exerts traction on the lever. The object of the initial movement of the arm, is that it may, through the medium of the interposed coin, push the dog out of engagement with the lever, before it exerts a pull thereon. As soon as the dog is free of the lever, the weight of the coin will raise it and the coin will roll into lower chute 62 which is suspended from the transverse bar 58, down which it falls into a till or box, 63, access to which may be had through a door-64- in a side wall. A door 65 affords means of access to the interior of the column for the purpose of refilling the tank. It is thought that the foregoing descriptlon 1s suificientto enableanyone skilled in th art pertaining thereto to make and use the same.

Having thus described it, what I claim is: 1. In a device as characterized, a frame, dlspensing means positioned therein, a lever pivotally connected with said frame and with said means, a reciprocable member, an arm pivotally connected with said member and with the lever, a detent normally engaged with said lever to prevent movement thereof and means for interposing a token between said arm and said detent whereby an initial movement of the arm will release the detent.

2. In a device as characterized, opposed supports, a pump positioned therebetween and pivotally connected to one thereof, a lever pivotally connected to the other support, said pump comprising a barrel and an extended rod, the outer ends of said lever and of the rods being pivotally connected, a member slidably associated with the second named support and an arm pivotally connected with said slidable member at the upper end thereof and with said lever at the outer end thereof, the arrangement being such that vertical movement of the sliding member will draw out the pump rod, a detent normally engaged with the lever and means for interposing a coin between said arm and the detent, whereby upon actuation of the sliding member initial movement of the arm, will through the medium of the interposed coin, disengage the looking element and permit continued movement of the sliding member to move the lever.

3. In a device as characterized, opposed supports, a pump positioned therebetween and pivotally connected to one thereof, a lever pivotally connected to the other support, said pump comprising a barrel and an extended rod, the outer ends of said lever and of th rod being pivotally connected, a member slidably associated with the second named support and an arm pivotally connected with said slidable member at the upper end thereof and with said lever at the outer end thereof, the arrangement being such that vertical movement of the sliding member will draw out the pump rod.

l. A member slidably mounted on a fixed support, a lever disposed at an angle to said support and pivoted by one end thereto and movable in a plane parallel with said sliding member, an arm pivotally connected tothe upper end of the sliding member and having a lost motion connected with the free end of the lover, a locking element adapted to be engaged with the lever, means for interposing a coin between said arm and the locking means, whereby upon actuation of the sliding member an initial movement of the arm, will through the medium of the interposed coin, disengage the locking element and permit continued movement of the sliding member to move the lever.

5. A sliding member mounted upon a fixed support, a lever pivoted by one end to and extending upward at an angle from said support, said lever being capable of movement in a plane parallelwith the sliding member, an arm pivotally connected with the upper end of the sliding member and having a slot near the other end thereof engaged over a pin extended from the lever near its outer end, a dog engaged with the lever and adapted to prevent movement thereof, and means for interposinp; a coin between said arm near its connection with the lever and the dog, the arrangement being 10 lever and permit of its actuation by the con- 15 tinued movement of the sliding member.
